One Loop Calculation of Cosmological Constant in a Scale Invariant Theory

Pankaj Jain, +1 more
- 15 Feb 2009 - 
TL;DR: In this paper, the cosmological constant in a scale invariant scalar field theory is computed and the scale invariance is broken by a recently introduced mechanism called cosmologically symmetry breaking.

Non-relativistic matter and dark energy in a quantum conformal model

Gopal Kashyap, +2 more
- 15 Feb 2016 - 
TL;DR: In this article, the authors consider a generalization of the Standard Model whose action displays conformal invariance in d dimensions and show how dark energy and dark matter arise in this model.

Quantum Gravity with Higher Derivative Terms

J. Julve, +1 more
- 01 Jul 1978 - 
TL;DR: In this article, a renormalizable (but perturbatively nonunitary) model of quantum gravity is considered, which includes quadratic terms in the curvature tensors, and one-loop counterterms are calculated for this enlarged action by using the background field method in the context of the dimensional regularization scheme.

A general gauge calculation of the graviton self-energy

D.M. Capper, +1 more
- 02 Oct 1978 - 
TL;DR: In this paper, the one-loop graviton contribution to the graviton self-energy is calculated in a general gauge and the Slavnov identities are shown to be satisfied, but it is found that it is impossible to choose the gauge parameter such that the counterterms are generally covariant.

Cancellation of one-loop contributions to the cosmological constant in quantum gravity☆

Mark T. Mueller
- 29 Dec 1983 - 
TL;DR: In this article, the one-loop contributions to the induced cosmological constant were computed in a theory of gravity with no cosmology term present in the classical action, and with no coupling to matter.

Frequently Asked Questions (1)
Q1. What are the contributions mentioned in the paper "Two-loop corrections-to- the cosmological constant*" ?

In this paper, the authors used the arbitrary-dimension unregulated quantization procedure of, M. Mueller, Ia1 who found that the diagrams that contribute to the cosmological constant vanish even when no regularization method is specified.
